Abstract According to the observation data of gPhone101# gravimeter in Zigui during 2012-06-2014-08, the corrected gravity residuals reflect the gravimetric response caused by reservoir impound changes. For different impound stages, gPhone101# gravity residual shows different response characteristics. Thirty meters elevation fluctuations of water level can cause a 70 μGal gravimetric response. A gPhone can detect the gravimetric response of Three Gorges Reservoir area effectively. However, local rainfall hydrological effects are also important contributors to gravimetric response and should not be neglected when we detect the influences of impound.
